Title: Liquid level detecting device
Inventor: KAWAMOTO AKIRA
IPC: G01F23/292
Filed: 1981-06-27
Abstract: PURPOSE:To detect the liquid level optically by providing a changing part, wherein a light guiding axis advances in a space, at a part of a light guiding rod part, introducing the liquid level detecting liquid in the space part, and detecting the light guiding degree of the light guiding rod body. CONSTITUTION:At the light end part of the light guiding pipe body 1, a light source 2 is provided. A detector 3 which detects the light guiding degree is provided at the terminating end surface of the light guiding rod body 1. The part of the light guiding pipe body 1 is changed so that the light guiding optical axis 4 advances in the space. For example, as shown in the Figure, a U-saped bent part is provided. When said bent part 5 is located in the air, a light beam 6 in the light guiding rod body 1 is repeatedly reflected by the inner surface as shown by the solid line and guided to the detector 3. Meanwhile, when the part is located in the liquid, the critical angle at the interface of the light guiding rod body 1 and the liquid 7 becomes larger than that in the air. The light beam is not reflected by the inner surface as shown by a broken line and transmitted through it. Therefore when the part is located in the liquid, the light receiving degree of the detector 3 is decreased.

IPC: F02D41/00
Filed: 1986-04-30
Abstract: PURPOSE:To reduce the occurrence of unevenness in an air-fuel ratio at each cylinder, by a method wherein a reference value, based on which an air-fuel ratio is controlled, is stored, and when a deviation between the detecting value of an oxygen concentration proportional type O2 sensor and a desired value is below a given value, based on a fluctuation in a detecting air-fuel ratio, a correction value of each cylinder is calculated for renewal.

Based on an average value thereof, a correction factor, on which feedback control is made, is computed, and feedback control is made on a desired air-fuel ratio responding to an operating state. When a deviation between an average air-fuel ratio and a desired air-fuel ratio is below a given value, the electronic control device 6 calculates and renews the correction factor of each cylinder, stored in a memory according to an intake air absolute pressure and the number of revolutions, based on the detecting value of O2 sensors 4 and 5 sampled at a timing responding to each cylinder.

Title: Pulse burner
Inventor: ISHIGURO SHOSUKE
IPC: F23C15/00
Filed: 1988-04-22
Abstract: PURPOSE:To improve durability and reduce noise, by installing a plate-shaped deflector at an air suction port, covering said air suction port, and driving a blower continuously during the operation of a pulse burner. CONSTITUTION:When starting a pulse burner, a control device 50 sets an opening of a gas valve 45 and a rotary speed of a blower 19 so that they may be proper to start the burner. The gas supplied by way of a gas suction valve 35 and the air supplied by way of an air suction port 25 are mixed in a mixing chamber 20, introduced into a combustion chamber 10, ignited by sparks of an ignition plug 15, and subjected to momentary combustion, thereby generating high temperature and high pressure combustion gas. A direct reverse flow from the air suction port 25 due to a momentary high pressure within the mixing chamber 20 is first inhibited by a deflector 30 which is against the reverse flow of the air. The reverse flow which bypasses the deflector 30 is temporarily inhibited by the inertia of the air. As a result, only a slight amount of air flows back from the air suction port 25 until the next suction cycle comes around. This construction eliminates the need for installing to the mixing chamber 20 a valve plate which must make a reciprocating motion to inhibit the reverse flow of the air, thereby preventing the generation of noise and the drop in the durability as well.
